Bodyguard, The (1992) - Details

Someone is threatening singing superstar Rachel Marron (Whitney Houston),
and ex-Secret Service agent Frank Farmer (Kevin Costner) is hired to protect
her. Farmer has to contend with the singer's indifference to security, her
entourage (who care more for their place in her career than for her safety),
her obsessed fans, her jealous sister ... and somewhere in the night, a
professional killer who can't be eluded, can't be caught, and can't be
called off.
